[PATCHv5 net-next 00/10] OVS conntrack support
The goal of this series is to allow OVS to send packets through the Linux kernel connection tracker, and subsequently match on fields populated by conntrack. This version addresses the feedback from v4, mostly minor fixes, including shifting the conntrack init into the per-namespace functions rather than per-datapath and ensuring the ct_mark/ct_label attributes are re-serialized when userspace dumps the actions. Users attempting to specify actions that set ct_labels with a length longer than the supported length will now get flow rejections. This series also rebases against the latest conntrack zone changes. This functionality is enabled through the CONFIG_OPENVSWITCH_CONNTRACK option. The branch below has been updated with the corresponding userspace pieces: https://github.com/joestringer/ovs dev/ct_20150818 Joe Stringer (10): openvswitch: Serialize acts with original netlink len openvswitch: Move MASKED* macros to datapath.h ipv6: Export nf_ct_frag6_gather() dst: Add __skb_dst_copy() variation openvswitch: Add conntrack action openvswitch: Allow matching on conntrack mark netfilter: Always export nf_connlabels_replace() netfilter: connlabels: Export setting connlabel length openvswitch: Allow matching on conntrack label openvswitch: Allow attaching helpers to ct action include/net/dst.h | 9 +- include/net/netfilter/nf_conntrack_labels.h | 4 + include/uapi/linux/openvswitch.h| 58 +++ net/ipv6/netfilter/nf_conntrack_reasm.c | 1 + net/netfilter/nf_conntrack_labels.c | 34 +- net/netfilter/xt_connlabel.c| 16 +- net/openvswitch/Kconfig | 11 + net/openvswitch/Makefile| 2 + net/openvswitch/actions.c | 229 +++-- net/openvswitch/conntrack.c | 723 net/openvswitch/conntrack.h | 78 +++ net/openvswitch/datapath.c | 86 +++- net/openvswitch/datapath.h | 13 + net/openvswitch/flow.c | 6 +- net/openvswitch/flow.h | 11 +- net/openvswitch/flow_netlink.c | 129 - net/openvswitch/flow_netlink.h | 13 +- net/openvswitch/vport.c | 1 + 18 files changed, 1317 insertions(+), 107 deletions(-) create mode 100644 net/openvswitch/conntrack.c create mode 100644 net/openvswitch/conntrack.h -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
